Change History: WebCVS Log

OVERVIEW

This module is an implementation of sulfate chemistry. It contains tracer emissions and chemistry. The chemistry is partly based on MOZART. The change of concentration of SO2, DMS, SO4, MSA and H2O2 are calculated using monthly mean concentration of OH, HO2, jH2O2, NO3, O3, pH. The emissions include: - DMS from seawater - SO2 by fossil fuel, biomass burning, non-eruptive volcanoes and aircraft - SO4 by fossil fuel

PUBLIC INTERFACE

atmos_SOx_init:
The constructor routine for the sulfate module.
atmos_SOx_end:
The destructor routine for the sulfate module.
SOx_source_input:
This subroutine read the monthly mean concentrations of OH, HO2, NO3, O3, and the monthly photodissociation rates jH2o2 and pH, as well as the emissions for DMS, SO2, and SO4 *****WARNING: To save space only the actual month is kept in memory which implies that the "atmos_SOx_init" should be executed at the begining of each month. In other words, the script should not run more than 1 month without a restart
atmos_DMS_emission:
The constructor routine for the sulfate module.
atmos_SO2_emission:
The constructor routine for the sulfate module.
atmos_SO4_emission:
The constructor routine for the sulfate module.
get_SO2_nerup_volc_emis:
This subroutine builds the emission rates of SO2 by non-eruptive volcanoes
